Lifter/camshaft/engine failure. GM knows this is an issue with these models/years. They only want to cover half of the repair sticking me with a bill for $5600. Safety is a concern because they know this is an issue and not issuing a recall currently. I waS driving when this happened which could have caused me to get into an accident. Very dangerous. Car is currently as GMC Started by showing low oil in between oil changes last year. Went in for an oil change and told them about it. Dealership told me it was the air hose box and that they didn't see any other issue. I believe they are told to lie to get each customer further out of warranty. I was driving and all of a sudden the car started violently shaking and lights started flashing at me.

Driving on the freeway the engine started making super loud knocking noises for while going 70mph . Then it immediately died everything turned off no power I was barely able to get it off the freeway while coasting. And my husband tried to push it off the road more but when it dies we are not able to put the car in neutral !! It’s a push button gear shift ! When there’s no power the buttons don’t work!! It was 105 degrees out that day in Sacramento , the car had zero power the battery is not the problem . The motor is blown and the car hasn’t started since that day. These cars are dangerous to just die in the middle of the freeway! The motor has already been replaced in Feb 2026, we bought it in march of 2026 with 57k miles on it. I added about 12k miles and the motor blew up again!

My 2021 GMC Yukon Denali features the 6.2L L87 V8 engine. This vehicle was previously serviced for the GM voluntary recall regarding engine bearing failures, and the dealership completed the remedy by inspecting the motor and changing the oil to the thicker 0W-40 specification. Since completing this recall fix, the vehicle has developed an intermittent rough idle and sputtering behavior. The dealership has been unable to duplicate the intermittent issue and claims it falls under normal behavior. I am filing this report because my vehicle is exhibiting post-recall remedy engine degradation, matching the exact failure patterns outlined in the NHTSA Engineering Analysis EA26005 escalated on August 20, 2026. This intermittent sputter represents a severe safety hazard regarding potential sudden loss of motive power while driving.

2022 GMC Yukon XL suffered catastrophic transmission failure at approximately 87,000 miles. An ASE-certified transmission repair facility determined that the torque converter failed, resulting in transmission damage requiring over $7,000 in repairs. GM declined any assistance solely because the repair was performed by an independent ASE-certified facility. I am concerned that a major transmission component failure at this mileage may represent a broader defect, particularly given transmission-related service bulletins and NHTSA Recall 26V085 affecting certain 2022 Yukon XL vehicles.
